你是在虚拟机中运行这个吗?

我在 Snow Leopard 上运行,并且必须不时从我的 Mac 访问 VS2010。我在虚拟机上遇到了类似的问题,但是当使用相同的代码时,它运行得很好。

我不太确定这是否是问题所在,但解决方案是在基于 Windows 的 PC 上尝试。如果它有效,那么至少您知道它与虚拟机相关。

Are you running this inside of a virtual machine?

I run on Snow Leopard and have to access VS2010 from time to time from my mac. I have had similar issues on a VM but when using the same code otherwise it runs perfectly.

I am not exactly sure if that is the issue, but the solution is to try it on a windows-based PC. If it works, then at least you know it is Virtual Machine-related.

无法在“appSettings file=...”中使用虚拟目录(甚至当前网站之外的文件;仅当前文件夹或子文件夹)。

跨项目共享设置的一种可能方法是在构建时进行 - 通过复制它,或者使用 VS 中的链接文件将其复制到发布时的文件夹中。

如果您确实需要在服务器上使用此功能,您可以尝试(尽管我不能说它的效果如何)

It's not possible to use a virtual directory (or even files outside of the current website; only the current folder, or a sub-folder) in 'appSettings file=...'.

One possible way to share setting across projects would be to do it at build-time - either by coping it in, or using a Linked File in VS to have it copied to the folder on publish.

If you really need this functionality on the server, you could try (though I can't say how well it would work) a Junction.

var injectModuleli = document.getElement('li.current');
var currentArrow = Elements.from('<strong class="arrow"></strong>');
currentArrow.inject(injectModuleli, 'top');

工作示例: http://jsfiddle.net/NGjgV/

var injectModuleli = document.getElement('li.current');
var currentArrow = Elements.from('<strong class="arrow"></strong>');
currentArrow.inject(injectModuleli, 'top');

您应该将 foreach 更改为

foreach($filters as $index => $filter)

并更新您的过滤器,

$filters[$index] = array(...);

我相信 foreach() 语句创建的 $filter 变量是数组中数据的副本,而不是对其的引用。

You should change your foreach into

foreach($filters as $index => $filter)

and update your filter by doing

$filters[$index] = array(...);

I believe the $filter variable created by the foreach() statement is a copy of the data in the array and not a reference to it.

PHP 通过引用传递问题 - 无法更改类型?

除了 baptiste 的 ggplot2 解决方案之外,这里还有一个使用 barplot 的简单示例:

Z <- sample(20,15,replace = TRUE)
barplot(Z,col = heat.colors(max(Z))[Z])

它会生成如下内容:

In addition to baptiste's ggplot2 solution, here's a simple example using barplot:

Z <- sample(20,15,replace = TRUE)
barplot(Z,col = heat.colors(max(Z))[Z])

which produces something like this:

一定要使用 De Bruijn idices。另外,请注意它们都是积极的。然后您可以在统一过程中使用负数。如果您想使用新索引,请使用全局索引。

Use De Bruijn idices for sure. Also, notice that they all positive. Then you can use the negative numbers during the unification process. If you want to use fresh indices, use a global one.

您的 SQL 语句应该是,

SELECT * from HAHA

 SELECT [Password] From HAHA

编辑:

您应该更改 ConnectionString

Your SQL statement should be,

SELECT * from HAHA

OR

 SELECT [Password] From HAHA

EDIT:

You should change the ConnectionString.

放弃 setTimeouts。在涉及窗口焦点时,它们的行为很奇怪。查看 jQuery 的自然 .queue() 功能。

ditch the setTimeouts. they behave strangely where window focus is concerned. check out jQuery's natural .queue() functionality.

当页面没有焦点时,javascript动画排队

该变量仅在您传递给 ready 函数的函数范围内定义。如果要引用它,需要在全局范围内声明它。 (只需删除 var 关键字)

The variable it's only defined in the scope of the function you pass to the ready function. If you want to reference it, you need to declare it in the global scope. (Just remove the var keyword)

错误 var 未定义 - 但在使用之前已定义 -

如果我理解正确,您希望在文本框旁边显示验证错误消息,而不需要在底部显示它们。如果是这样,请从页面中删除 ValidationSummary 控件。这会导致在放置验证器控件的位置显示错误消息。

希望这有帮助!

If I understood correctly, you want to display the validation error messages next to the textboxes and don't need to display them at the bottom. If this is so, remove the ValidationSummary control from the page. This results in displaying the error message where the Validator controls are placed.

Hope this helps!!

ssh 返回相关命令的返回值,如果 ssh 本身发生错误,则返回 255。只需检查该值并采取适当的措施即可。

ssh returns the return value of the command in question, or 255 if an error occurred in ssh itself. Simply check this value and take appropriate action.

有一种替代品叫做生皮 (rh),它更容易使用。而不是:

find /dev -maxdepth 1 -name 'abc-*'

你可以这样做:

rh -r /dev '"abc-*"'

-r 与“-m1 -M1”相同,与 find 的“-min深度 1 -max深度 1”相同,只是短得多。

Rawhide (rh) 可从 https://raf.org/rawhidehttps://github.com/raforg/rawhide。它至少可以在 Linux、FreeBSD、OpenBSD、NetBSD、Solaris、macOS 和 Cygwin 上运行。

免责声明:我是 rawhide 的当前作者

There is an alternative to find called rawhide (rh) and it's much easier to use. Instead of:

find /dev -maxdepth 1 -name 'abc-*'

You can do:

rh -r /dev '"abc-*"'

The -r is the same as "-m1 -M1" which is the same as find's "-mindepth 1 -maxdepth 1", just a lot shorter.

Rawhide (rh) is available from https://raf.org/rawhide or https://github.com/raforg/rawhide. It works at least on Linux, FreeBSD, OpenBSD, NetBSD, Solaris, macOS, and Cygwin.

我认为,完成日期时间自动填充的最佳方法是这样:

* @ORM\Column(type="datetime", options={"default"="CURRENT_TIMESTAMP"})

将逻辑放入构造函数不是正确的解决方案,因为设置默认值是SQL客户端的责任。如果您决定不再使用 ORM - 您将失去业务逻辑。另外,如果使用构造函数,您将无法向现有行datetime属性添加默认时间戳。

I think, the best way to accomplish autofill for datetime is to make like that:

* @ORM\Column(type="datetime", options={"default"="CURRENT_TIMESTAMP"})

Putting logic to constructor isn't right solution, because setting default values are SQL client responsibility. If you decide no longer use ORM - you will lost business logic. Plus, if using constructor you won't be able to add default timestamps to datetime attributes for existing rows.

原则 2.1 - 日期时间列默认值

我通过在我想要刷新的页面上的页面 div 中使用 data-cache="false" 属性解决了这个问题。

<div data-role="page" data-cache="false">
/*content goes here*/

</div>

就我而言,这是我的购物车。如果客户将一件商品添加到购物车,然后继续购物,然后将另一件商品添加到购物车,则购物车页面将不会显示新商品。除非他们刷新页面。据我所知,将 data-cache 设置为 false 指示 JQM 不要缓存该页面。

希望这对将来的其他人有帮助。

I solved this problem by using the the data-cache="false" attribute in the page div on the pages I wanted refreshed.

<div data-role="page" data-cache="false">
/*content goes here*/

</div>

In my case it was my shopping cart. If a customer added an item to their cart and then continued shopping and then added another item to their cart the cart page would not show the new item. Unless they refreshed the page. Setting data-cache to false instructs JQM not to cache that page as far as I understand.

Hope this helps others in the future.
